Lab Portfolio Assignments
Special Instructions

The laboratory portfolio assignments were developed originally for students taking BOT 202, Plant Biology on the Eastern campus. I have been placing photographic images on the Internet in an attempt to make as much of the laboratory materials as possible accessible to distance learners. Images can be found in the Plant Biology Image Gallery. The Lab Portfolio Assignments can be purchased from the Eastern campus bookstore. Following are some instructions for how to complete the assignments.

Portfolio #1: Plant Tissues and Primary Growth
For part 1, use any fresh plant material you have available, such as house plants or cuttings from outside. Monocots are generally recognizable by the parallel veins in the leaves and dicots can be recognized by the branching leaf veins. For part 2, use the Internet images of Helianthus (sunflower). For part 3, use the Internet images of Zea (corn). Both Helianthus and Zea stem cross-sections can be found under Herbaceous Stems. Use your text book to complete Table 1 in part 4.

Portfolio #2: Transport Processes
Individualized Study students will not complete this assignment.

Portfolio #3: Leaves
For parts 1 and 2, use any fresh leaves available to you. For part 3, use the Internet image of a Ligustrum (dicot) leaf. You will also want to examine the images of Nerium, Cluvia and Pinus to see examples of variation in leaf anatomy. No monocot leaf section is available at this time. Skip part 5.

Portfolio #4: Roots
For part 1, use any fresh roots you have available. A good way to get a good look at roots is to germinate a few seeds, such as radish, between layers of damp paper towels. For part 2, use the Internet image of Raphanus (radish), whole mount and Zea (corn), longitudinal section. Skip part 3. For part 4, use the Internet images of Ranunculus (Buttercup), both young and mature. For part 5, use the Internet images of Smilax roots. For part 6, use the Internet image titled Lateral root origin. All of these images can be found under the roots heading.

Portfolio #5: Secondary Growth
For part 1, use the Internet image of Tilia stem found under Woody Stems. For part 3, look at any wood rounds or tree stumps you have available. For part 4, use the Internet images of Pinus and Quercus (Oak) wood in all three sections, x-sec., tangential sec., and radial sec.

Portfolio #6: Kingdom Fungi
For parts 1 and 2, use the Internet image Zygomycotina, Rhizopus. For part 3, look at the images of lichens labeled Crustose Lichen, Ascocarp, and Fruticose Lichen. Use the image of Ascomycotina, Peziza ascocarp to see a cross-section of lichen tissue for part 5. For part 6, use a mushroom from the grocery store. For part 7, use the Internet image of Coprinus gills, Basidiomycotina.

Portfolio #7: Kingdom Protista
Algae are much less interesting to look at dead than alive. The illustrations in your text book are better than my slides for the algae, but I have put a few on the Internet that you can look at. Included are: part 1, Euglena; part 3, Diatoms; part 4, Volvox; part 6, Oedogonium; and part 7, Spirogyra. You will need to use your text book for parts 8, 9, and 10.

Portfolio #8: Kingdom Plantae: Non-vascular plants
The images for this assignment are all found under the heading Non-vascular plants (Mosses, Liverworts). For part 1, use the Internet image labeled Moss protonema. For part 2, use the image Moss gametophytes and sporophytes. For part 3, use Moss antheridia and Moss archegonia. For part 4, use Moss capsule. For part 5, use Marchantia thallus. For part 6, use Marchantia archegonia and Marchantia antheridia. There is no image available at this time for part 7.

Portfolio #9: Kingdom Plantae: Vascular, Seedless Plants
Images are not yet available for this lab.

Portfolio #10: Kingdom Plantae: Seed Plants
Images are not yet available for this lab.
